Are These Contests Even Real

First of all I want to say this: there were a lot of genuinely great models in this contest. Seriously. You could clearly see the amount of work behind them, thoughtful design, real functionality, refined details, test prints, iterations, proper assembly instructions. These are projects that took hours or even days to develop. Huge respect to the community for that.

Which is exactly why the list of winners feels so disappointing.

Looking at some of the awarded models something just doesn’t add up. One of them especially looks like pure AI slop. And I’m not saying that because I “don’t like it”, I’m saying it because the geometry speaks for itself.

It’s a simple shape broken into an absurd number of triangles. Completely unoptimized mesh. Anyone who works with parametric modeling or understands basic topology can immediately see this is not a manually designed model. It looks like raw generative output with zero cleanup.

The only part that actually looks human made is the base, just a simple cylinder added in Blender and booleaned to the rest. That’s it. The rest feels like a straight export from an AI generator.

The description reads like it was generated by AI.
The renders look highly suspicious, very much in the NanoBanana style.
On the cover and in the images there are engraved texts that don’t even exist in the actual model file. So the render shows one thing, the STL contains another. It honestly looks like even adding a simple text onto a cylinder was too much effort so it was just faked in the render instead.

Now let’s look at the official judging criteria:

-Innovation 25%
-Functionality 25%
-Visual Appeal 25%
-Completion 15%
-Relevance 10%

Where exactly is the innovation here?
Where is the real world functionality?
How was “Completion” evaluated if the model doesn’t even match what’s shown in the images?

If projects like this are winning what message does that send to people who actually design their models properly? People who care about clean geometry, optimized meshes, printability, structural thinking and real usability?

I’m not trying to attack anyone personally. This is about standards. From the outside it really raises the question whether the contest was judged according to the stated criteria.

I’ll be posting a few examples of models that didn’t win but clearly represent a much higher level of effort and craftsmanship. It’s honestly hard to understand how those lost to something that looks like ten minutes in a generator and a quick STL export.

I would really appreciate some transparency about how the judging was actually done, because right now it simply doesn’t align with the published criteria.

So… what do you guys think? Are these contests actually fair, or are they just set up?

I say NO as well.

With the added sentence: ‘It’s the taste of a chinese company.’ They have a completely different approach and taste - to both the themes and choosing winners. It’s also a kind of cultural thing. In addition to business sense, which models are suitable for advertising - in their eyes, not ours.

It’s a waste of time thinking about it. The issue has existed for as long as competition has existed. Even the first competitions were controversial in terms of the winners. The solution is to either ignore it or participate without any expectations.

I have seen models with ai and never printed winning a contest so….

I entered two contests early on. I designed special models for them. Most of them never even got looked at, let alone printed. My motivation went to zero after that. I design what I want and then I share it. :wink:

What surprised me more was that the picture frame won. Don’t get me wrong, it’s a great 3D model, but it’s not a new nor creative idea. Even the name “museum of Us” has been used for products on the market for a long time.

I have nothing against the creator, though! However, I’m not sure about awarding first place for an inspired idea from an existing product.

…on Reddit, TikTok, you can find it under the same name from a long time ago. Just as some retailers have been selling it under that name for some time. Long before the 3D model was released on MakerWorld. On TikTok, there are countless tutorials on how to make it yourself. Published years ago.


As I said, great work, that’s not my criticism! Again: I’m not criticizing the creator; it must have taken a lot of work.

  • I, personal opinion, just wish that a new and unique idea would have been in first place.

Well, with having had 20 years in the video game industry where we regularly created high-poly models, I’d say it looks like it was sculpted and then poly-reduced… but what do I know :man_shrugging:

Kind of you to highlight my design! I made the candy dispensers :smiling_face_with_three_hearts:

This is most likely it. Sometimes when I do procedural generation (geometry nodes in Blender), it leaves non-manifold mesh geometry. Sometimes I repair it manually, but other times the easiest fix is just to remesh it and decimate the result. It does leave you with an unoptimized mesh with topology unfit for a game, but it still works well enough for 3D printing.

I don’t really think they are legit tbh, and I’m not interested in spamming slop anyways which is what seems to work. A couple years back I (and a few other people that I thought were more deserving than me) had some high effort super popular models get no recognition while things that didn’t even follow the rules did, and I could go on about quality and how one of them had literally zero stats of any kind and still barely has any cuz it’s so… yeah I’ll stop there lol. Idk what the game is but I’m not on the inside of it.

I also have no interest in competing against people who are effectively stealing IP and using that built-in audience to their advantage, it’s crazy to me that they pick that stuff as contest winners. At some point there’s going to be articles about how models specifically endorsed by Bambu were removed due to trademark and copyright violations.

If you are not aware, Bambu Lab has been taken to court by Pop Mart.

Make a correlation graph between contest winners and weight of model (sale of plastic) and see what is the main criteria.

What soured me on the contests were the curated collections Bambu makes from the contest entries which short circuits other models that don’t make that cut.

People go to the curated collections because they are really some of the better models but that cuts traffic to the great unwashed masses actually entered in the contest.

I suspect they like the curated collections because they leave the low effort stuff behind but I would argue Bambu should curate the contests themselves. Slop has always been an issue but just gets ignored as long as Bambu creates a shadow contest like this.

But their platform. Contests have lost my interest.
